I'm new here so excuse me if I repeat a thread.... so my question is what is the biggest size tire can I put on a stock 18" rim without bulging? I think the width is 8.8" wide .... some say 285/65 or 60. Is this true ?

 

Go to tirerack and look at the specs to determine what the largest size is that has a recommended rim width that includes the rim width of your wheels.

 

Thx sir I will do just that

 

The factory 17's and 18's are only 7.5" wide, the 20's are 8.5"

 

I ran 295/70R18 Trail Grapplers without issue on my 2013.

 

Yes your right ... I happen to look at my tire specs on the inside of my door .... yes they are 7.5" wide ....

 

So no bulging? What about rubbing issues? I'll have to look into those .... is that size tire have more meat on it like are they taller in height ?

 

Again. tirerack.com look at tire specs for the size you are interested in.

 

10-4 thx

 

On a 295/70/18 tire rack says rim width range 7.5-10" so that size should be good
